Objective: This study was designed to evaluate diagnosis and complication, prognosis during clinical study of cases of intrauterine fetal death. Methods and materials: This is a clinical study of 56 cases of the intrauterine fetal death among 8064 deliveries at Seoul Sunchunhyang university hospital during 5 years from January, 1994 to December, 1998. Results: The incidence was 0.7%. The age distribution of mothers was 18 - 44 years and was highest in the 25 - 29 years range(46.4%). The parity was the most highest in the nulliparous group(51.8%). The most common gestational weeks was 20 - 28 weeks gestational period(46.4%), and most common presentation was cephalic(73.5%). The most common weights of the intrauterine fetal death was from 5,00gm to 1,000g(48.2%). The mode of the most common delivery was the induction of delivery(57.2%). The etiologic factors were: unknown(42.9%), preeclampsia(17.9%), chorioamnionitis(14.3%), congenital anomaly(12.5%), abruptio placenta(7.1%), cord complication(3.6%), placenta previa, death of one for twin. There were 2 cases of maternal complication(DIC, Uterine atony). Conclusion : Intrauterine fetal death should be diagnosised early and treated properly to reduce risk of the maternal complication.

Two cases of primary small cell carcinoma of the ovary occurred. One was a case of 43-year-old woman associated with hypercalcemia and the other was a case of 40-year-old woman with pulmonary type. Ovarian small cell carcinoma of the hypercalcemic type have clinicopathological, immunohistochemical, ultrastructural, and flow cytometric features that from differ from those of small cell carcinomas of the pulmonary type. It is important for therapeutic reasons to distinguish these two types of ovarian tumors from each other and from a variety of malignant small cell tumors that ovary primarily or secondarily. So, we reported these cases with a brief review of the concerned literatures.

본 연구에서는 유치 수복물의 불소 방출 여부에 따른 주변 법랑질의 탈회 저항성과 재광화 효과를 살펴보고자 하였다. 건전 유전치 48개를 16개씩 임의로 세 군으로 나누어, FiltekTM Z250(1군), F2000(2군), KetacTM N100(3군)을 사용하여 제조사의 지시에 따라 충전하였다. 3일 동안 인공 우식 병소를 유발한 후, 14일 동안 인공 타액에 담가 재광화를 유발하였다. Quantitative light-induced fluorescence(QLF)를 이용하여 실험 단계와 시간에 따른 무기질 소실량(ΔQ)의 변화를 관찰한 결과는 다음과 같다. 1. 탈회가 일어난 인공 우식 병소의 ΔQ 값은 3군, 2군, 1군 순으로 작게 나타났고, 이 중 3군은 1군에 비해 유의한 탈회 저항성을 보였다. 2. 1군, 2군, 3군 모두 재광화 1일 후부터 초기 인공 우식 병소의 ΔQ 값과 비교 시 유의한 차를 보였으며, 관찰 기간 동안 지속적인 증가 양상을 나타내었다. 3. 재광화 속도를 의미하는 Δ(ΔQ)/일 값은 각 군에서 처음 1일 동안 유의성 있게 크게 나타났으며, 그 이후 급속히 감소하였다. 4. 수복 재료에 따른 재광화 정도는 각 군 간에 유의한 차이가 없었다. The objective of this in vitro study was to detect and monitor demineralization and remineralization of primary teeth according to restorative materials using quantitative light-induced fluorescence (QLF). A single bur hole was drilled on the each sound forty eight primary anterior teeth, and the specimens were divided into three groups. The cavity was restored with FiltekTM Z250(Group 1), F2000(Group 2), KetacTM N100(Group 3) following the manufacturer's instructions. The teeth were subjected to the demineralizing buffer for 3 days, and then subjected to a remineralizing buffer for 14 days. The change of mineral loss(ΔQ) according to the stages was evaluated by QLF and the following results were obtained: 1. When demineralization was done, ΔQ was increased as follows. : Group 1 (-110.79 ± 27.77) < Group 2 (-104.84 ± 28.95) < Group 3 (-90.16 ± 21.87) : Resistance to demineralization was statistically significant in Group 3. 2. There was a statistically significant increase in ΔQ of all groups since 1st day of remineralization 3. The rate of remineralization, Δ(ΔQ)/day, showed significant high value in each group on the 1st day then decreased rapidly. 4. There was no statistically significant difference in the degree of remineralization among restorative materials.

본 연구는 지배구조가 경영성과에 어떤 영향을 미치는지를 측정하고자 한다. 종속변수로 토빈 Q를 이용하였고 독립변수로는 대주주인 1인 지분을, 이사회의 규모, 외국인 지분을, 주거래은행 차입금 비율등을 이용하였다. 연구결과 대주주1인 지분율과 외국인 지분율 그리고 주거래은행 차입금비율은 토빈의 Q와 양의 관계를 가지는 반면 이사회의 규모는 음의 관계를 나타내었다. 특히 외국인 지분율은 강한 양의 관계를 보임으로써 외국인이 상대적으로 경영성과가 우수한 기업에 많이 투자하고 있다는 것을 발견할 수 있었다. This paper examines the impact of corporate governance on financial performance. We used Tobin's Q as dependent variable and large shareholder ratio, board size, foreigner's shareholder ratio and main bank debt ratio as independent variables. The Empirical tests indicate that large shareholder ratio, foreigner's shareholder ratio and main bank debt ratio have positive relations to Tobin's Q, but board size has negative relation to Tobin's Q. Especially, foreigner's shareholder has strong positive relation to Tobin's Q, so we find foreigners invest their fund to relatively better corporations.

Allylthio group of allicin and other organosulfur compounds which are isolated from garlic is considered as a pharmacophore, a key structure component of the molecule which is due to biological activities. In the foregoing studies various 3-alkoxy-6-allylthiopyridazine derivatives (K-compounds) were synthesized and their biological activities were tested in test animals. They showed good hepatoprotective activities on the carbon tetrachloride-treated mouse and aflatoxin B1-treated rats and chemopreventive activities on hepatocarcinoma cells in rat as expected. Now two pyridazine derivatives whose oxygen atom at 6-position of 3-alkoxy-6-allylthiopyridazine is displayed by sulfur(S) were synthesized and their activities were synthesized and their activities were tested in vitro against SK-Br3 human breast cancer cells and Hep-G2 human liver cancer cells. Thio-K6 and Thio-K16 showed good chemopreventive activities on hepatocarcinoma and breast cancer.

The purpose of this study was to examine the relationship between the career maturity level of adolescent students and work values and to provide basic materials that can be some help to the career guidance and counseling. To achieve this purpose, research problems were as follows; First, this study was to analyze the relationship between the career maturity level and the work values. Second, this study was to investigate the most important predictive variables which influence on the career maturity. The samples consisted of 600 students (300 boys and 300 girls) from 7th grade, 9th grade and 11th grade students in Taegu, Korea. Students were administered the Career Maturity Inventory (CMI) by Crites(1973), and Work Value Inventory (WVI) by Super(1975). The CMI and WVI are self-report written instruments. For the statistical analysis, Pearson's coefficient correlation and stepwise multiple regression by SAS program have been applied. The results of this study were as follows; First, the correlation between the career maturity and intrinsic work values such as altruism, intellectual stimulation showed statistically significant positive correlation at P<.05 level. 7th graders have positive correlation at P<.01 level in achievement, altruism, intellectual stimulation and independence, and 11th graders in activity, esthetics, intellectual stimulation and independence. 9th graders have negative correlation in intrinsic and extrinsic values. Second, there were no influencing predictive variables of work values, grade and gender on the career maturity level, but there were statistically significant relationships at P<.05 level. Variables affecting career maturity were showed as the following order: intrinsic work values, extrinsic work values, gender and grade.

The running mechanism of flexible and thin foil above rotating protrusion is analyzed throught a numerical simulation. The scope of analysis is confined to the phenomena of elastohydrodynamic lubrication between the rotary drum with a running protrusion and thin foil. This mathematical analysis is based on the modified Reynolds equation and the equation of plate, considering the protrusion geometry and the effect of geometric nonlinearity. Finite element method is adopted as a numerical simulation method to solve the above coupled nonlinear equations. In numerical analysis, the effects of head window in rotary drum are evaluated. And the analysis results of the window model are compared with the those of no window model.
